Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483996, here are decompositions:

17 + 31483979 = 31483996
83 + 31483913 = 31483996
107 + 31483889 = 31483996
113 + 31483883 = 31483996
197 + 31483799 = 31483996
263 + 31483733 = 31483996
347 + 31483649 = 31483996
419 + 31483577 = 31483996

Showing the first eight; more decompositions exist.
